I have been experimenting with my exhaust as of late. I own a 1994 LT1 6-speed convertible with LT4 Hot Cam and LT1 Ported Heads. One of my OEM catalytic converters broke loose and well... expired. So I pulled them off for good measure and headed back to the track and was amazed at the results. .2ET and 2mph improvement in the 1/4 mile. 12.77 at 110.86. Also, with a 90 horsepower jetting NOS, a time of 11.45 at 122.86. The only drawback to the cat-less system is the ungodly exhaust fumes. Does anyone know what type and where I can get some high flow cats without losing this 20 hp increase. Thank you in advance for your thought and comments. They will be greatly appreciated.

Congrats on the new found HP, but the real experiment is with eliminator pipes. You not only took the cats out but the entire cat-cack system.

You can buy Random Technology cats directly or from vendors.

I bought some Catco Bullet cats($125 for two). They flow way better than stock. I felt this mod when I had it done.

My muffler guy got them for me. You can also order them through Summit Racing.

Here's the link to the exact part I got. It doesn't look like the picture at all. Mine is a 4" diameter round cat. It is around 6-8" long and has a 2.5" inlet/outlet.

You can cut the neck of the Catco cat to make it 3". It's easy to do that.
